With the right indications, partial knee arthroplasty (PKA) is an
alternative to both total knee arthroplasty (TKA) and high tibial
osteotomy. The Oxford Partial Knee includes options for both medial and
lateral compartment replacement as well as cemented and cementless options.

Unique Design

The Oxford Partial Knee has a unique mobile-bearing design which was
patented by John Goodfellow and John O’Connor in 1974, and first used
in 1976. The Oxford PKR is the only partial knee that's been clinically
proven in survivorship at minimum 10, 15 and 20 years.1-7

Also, the Oxford PKR is a bi-cruciate retaining knee, meaning the
healthy ACL and PCL are kept intact. This provides stability and
maintains natural kinematics for the patient after surgery. We believe
the retention of the ACL is an important contributor to reported
higher patient satisfaction following Oxford PKR surgery vs. TKR8.

Advantages of PKA vs. TKA:

Higher patient satisfaction may be the result of the many benefits
that PKA offers patients, such as:

A more natural fit than TKA, with only the affected medial
compartment being replaced9

Improved range of
motion10-12*

Preserving more healthy
bone12*

Better functionality12 and more
natural motion12 than TKA

Faster recovery and
shorter hospital stay than TKA10

Fewer and less
severe complications including less morbidity compared with
TKA13,14

Studies also show that if partial knee replacement is performed
early in the disease process, it can prevent the spread of arthritis,
providing a long term solution15.
